LINCO has a variety of sized rubber caster wheels including small rubber caster wheels used on the smallest of projects. A drawback of common rubber caster wheels is that they compress and flatten out under a heavy load, thus making them difficult to push. Hard rubber caster wheels help to alleviate this problem by making the rubber more compact and harder to flatten out under a load, however they are limited in how much load they can hold before they begin to buckle under a heavy weight. For your heaviest cargos we recommend the solid rubber caster wheels which have no air inside of them and they are extremely strong and can withstand very heavy loads. LINCO offers rubber caster wheels in a variety of sizes, colors, and hardness so you are sure to find the exact wheel for any repair or to complete any project requiring rubber caster wheels. LINCO rubber caster wheels are your best option when looking for a wheel that is quiet and non-abrasive to expensive high-quality floors.
